+# On alpha-osf, it appears that libtermcap and libcurses are not compatible.
+# There is a very specific comment in /usr/include/curses.h explaining that
+# termcap routines built into libcurses must not be used.
+#
+# The symptoms we observed so far is GDB unexpectedly changing
+# the terminal settings when tgetent is called - this is particularly
+# visible as the output is missing carriage returns, and so rapidly
+# becomes very hard to read.
+#
+# The readline configure script has already decided that libtermcap
+# was enough for its purposes, and so decided to build readline using
+# libtermcap. Since the TUI mode requires curses, building GDB with
+# TUI enabled results in both libraries to be used at the same time,
+# which is not allowed. This basically means that GDB with TUI is
+# broken on alpha-osf.
